Abstract

We demonstrate an efficient optoelectronic platform using WSe₂/hBN/Bi₂Se₃ van der Waals heterostructures to manipulate the photocarrier polarization and dynamics. Our observations are corroborated by the comprehensive polarization, external electric field, and two-pulse delay dependence behaviors.
